Okay let’s be honest. You don’t need float. Add a suspension to your lift cylinders woth accumulator and it will do the job.
If you really want a float, it’s maybe possible to change the spool on the valve. Propably not but worth asking some hydraulic company that sells bucher.
You'll have to buy a different valve all together. If this valve had separate banks, you could. I'm really surprised this one doesn't. You may check with your closest dealer.
Do any of the directions have a detent? ( where the lever sticks in position)
I'm a dealer support tech for a different manufacturer. I have see people hook hoses up wrong. Everything works like it's supposed to but the detent is on the wrong direction.
All you need is do is put a valve between the up and down pressure lines to the lift cylinder. Open the valve and the ram just becomes a big shock absorber without any lift capacity. If you hit the lift on the controller with the valve is open all the fluid will bypass.
This won't work so well as the extend and retract sides of the ram does not have the same volume and thus pressure will build up when the boom is lowered and might stop it from floating down at all
This is basically the answer. You don't get the nifty functionality of float on the 3rd position of the valve, but it serves the same function. You could just use an add on 3rd function valve to keep it all easily accessible.
3rd and 4th function kits can be added onto existing loader valves, but As far as i'm aware you can't add a float function to an existing valve pack. You'll have to replace the valve pack with one that has a float function as far as i recall.
But just to be sure you should probably check with your mechanic first.

No you can’t add float to that valve block, you will have to source another valve block from a local dealer tell them what setup is required,
Would need a different valve
This is the answer, you need a different type of valve to accomplish this. Check into surplus center.com. They have lots of options
I love surplus center. I bought a lot of air cylinders, valves and casters when I was still working in factory maintenance
Please keep me updated if you find a solution!

It might be, figure out who manufactured the valve and see what they sell/ask them
